RESEARCH DESCRIPTION
Our group investigates a wide range of collective quantum phenomena arising from the interplay of interactions with constraints imposed by symmetry and topology in quantum materials. Our research is motivated by experimental developments in the field of condensed matter physics as well as by an intrinsic desire to understand questions of fundamental scientific interest in quantum physics.
Our group currently works on developing theoretical frameworks to understand the interplay between symmetry broken and topological orders in quantum matter. We are particularly interested in studying modern quantum materials, where electrons and spins organize into highly entangled phases of matter characterized by topologically protected surface states and emergent fractionalized quasiparticles. These phases of matter have non-trivial entanglement patterns, which make them platforms suitable for applications in quantum information science. Our research employs tools from quantum mechanics, quantum field theories and quantum information to characterize these phenomena. An overview of our research interests can be found under the Research tab.
